Add Later/Earlier

Add Later

The 'Add Later' option on add-item forms allows you to mark an item to become visible only at the exact time you've specified. Before that time has come, the item will not be viewable anywhere in the public part of your site.

This date must be in the future, unless the 'Allow posting to the past' option is enabled for the blog to which you want to add the item.

Allow posting to the past

When enabled, you'll be allowed to specify the date on which an item should be added, and to edit the timestamp of already existing items.

Change post date/time

The 'Update Timestamp' option allows you to change the posting date and/or time of an item. If you changed the content of an item, this is a way bring the story back to the top of your front page.

But, the unique id connected to the item will not change, so your visitors can still find out that the item was originally posted later than items with a lower id.

Drafts

Draft items are not yet viewable in the public blog. They might come in handy when you are working on a story, and something comes in between. Your draft items will be listed on the main page, so you can continue your work when you have the time to do so.

When editing drafts, choose the 'Add now' radiobutton and hit the 'Edit item' button to make them visible.

Extended part

Items have an optional extended part that you can use for continued stories. e.g. when a story is too long to put on the main page of your blog, you can write an introduction in the body part and the rest in the extended part. When viewing your main blog page, you will then see 'read more' links (as defined by the templates).

If you want to write an introduction only for some of your items, you could use the smartbody template variable to make a selection out of the body text and the extended text.

Short Blog Name

The short blog name is used mainly in the admin area to indicate which items are associated with which blog.

It can also be used in alternative index files, to make a second weblog available:

<?
	include('./config.php');
	selectBlog('myshortblogname');
	selector();
?>

Default Skin

The default skin selected in the blog settings is the skin that should be used when the blog is displayed, and there is no other skin selected (through arguments in the URL)

Notify Address

This option contains one or multiple e-mail addresses to which notification e-mails should be sent when new comments are added. Leave empty if you don't want notification. The given e-mail addresses must, of course, be valid.

If you're using multiple addresses, you should use a semicolon (;) as a separator.

Max Amount of Comments

This is the maximum number of comments that will be shown on the main page. This is NOT a restriction on the total number of comments that can be made. On the detail pages, all comments will be shown, even if there are more than the maximum amount chosen.

Note: Inside templates, this variable can be overridden by an optional parameter of the comments templatevar.

Time Offset

If the time on your server is not equal to the time where you live, you might want to add an offset to the server time in order to get the correct time. Use negative values to subtract (negation sign). The current server time is listed as a reference.

Example

If your local time is 20:35 and the server time is listed as 14:35, you'll need to set the time offset equal to 6 in order to get your blog time to 20:35

Note: Fractional offsets can be used as well, for people living in half time zones. e.g. an offset of 1.5 equals an offset of 1 hour and 30 minutes.

Update File

Nucleus can edit a file for you whenever a new item is added to the blog. The contents of that file will be a timestamp of the last change. The use of such a file could be useful for services which check a file on your server once in a while to see if there were updates, and generate 'updated weblogs' from that. Pointing them to your main blog could cause false update warnings to be sent out when visitors add comments or when you change something to the skins or templates.

When you don't need an update file, just leave the field empty.

Please note that the location of the update file is relative to the admin-area, so you might want to use an absolute path (something like /path/to/your/website/update.txt). Also make sure the update file already exists and is writable (chmod it to 666 if you want to be sure).

Blog Admin

Blog administrators have the following extra rights:

• They can manage the team
• They can edit blog settings
• They can edit/delete all items by all authors (from the blog of which they are admin)
• They can delete the blog

A blog can have multiple admins, but there must be at least one admin at all times.

Administrator Privileges

A so called super-admin has full access to all functions and all weblogs, even if she is not on the blog team.

On top of that: a super-admin has the right to create new weblogs, to change general settings, to change templates, to change skins and to manage the members (creation/ manipulation/ deletion of members).

Usually, there will be only one super-admin, the site administrator.

Can Login?

As a superadmin, you can disallow individual members to login to the admin area.

Default Blog

This is the blog that will be used when no other blog has been specified in the request.

Base Skin

The option tells Nucleus which skin to fall back to when no such decision can be automatically made. This happens when skin parts are empty, when no blog or skin is implicitly/explicitly selected.

Most users don't need to worry about this setting.

Cookies

Cookie Lifetime

When a member logs in, a cookie is stored in his browser, so she doesn't need to log in again when she comes back the next day. The lifetime of this cookie decided when it will become invalid:

• Session cookies get deleted when you exit the browser
• Cookies with a lifetime of one month will stay on the computer until you don't use/visit the site for a month. Using this option, you'll never have to login again (unless you've logged out yourself, or logged in from another computer)

Cookie Path & Cookie Domain

These settings are advanced settings. Normally, you shouldn't change them at all. In that case, cookie path is a simple slash ('/') and cookie domain is empty.

Secure Cookies

Normally, this should be set to 'no'. You should only set it to 'yes' when you have a HTTPS url and want cookies only to be sent over such a https connection.

'Last Visit' Cookie

You can setup Nucleus to store a cookie in which the time of the visitors last visit is stored. This can be used to put indications next to new items

Language

You can choose a language to be used when nucleus creates content for you. The content generated by Nucleus includes the admin-area, the error messages, forms in skins, ...

There are two places where a language can be chosen: the global site settings include a language option. Next to that, logged in members can override this setting if they want to.

When both of these settings are invalid, 'english' is used as the default language.

Note: Extra language files can be downloaded from the Nucleus Website. (opens a new window)

Account Creation

You can either allow or disallow your visitors to create their own 'member' account. They won't be allowed to add items to a blog (unless the admin adds them to a team), but they can login to the administration area and change their settings, and even delete or modify the comments they made.

New Member: can login ?

When you allow creation of member accounts by your visitors, this setting defines whether or not accounts created in that way will have the ability to login to the administration area.

Message Service

For the privacy of your members, you can hide all e-mail addresses and allow members to send an e-mail message to each other through the script. The message that will be sent out will however contain the e-mail addresses of both users, so they can then do continued communication through regular e-mail. This service can be disabled.

Non-members

By default, non members cannot use the message service (because there's no way to check the validity of the e-mail address they enter). You can relax this restriction by allowing non-members to use the message service too. When submitting a message, they will be asked to enter their e-mail address, which will show up in the From: headers of the e-mail you receive.

Disable Site

It's possible to disable your entire Nucleus site. You might want to do this when you are doing some configuration, or when something went horribly wrong :-)

The URL that needs to be configured is an URL to which the visitor will be redirected.

Exceptions: the admin-area is still available, and super-admins can still see the entire site. (don't forget to re-enable your site afterwards ;-))

URL Mode

Using this option, you can switch between URL styles:

• Normal: URLs looking like http://host/index.php?itemid=1234
• Fancy: URLs looking like http://host/item/1234

Note: In order to get the 'Fancy URL' mode working, some extra actions are required. They're described in the Tips & Suggestions (opens in new window)

Templates: Items

When items are shown, the following setup is repeated for each item:

item header
item body
item footer

These three blocks all refer to a template-part, which define what the result looks like.

Variables

Within these template, a series of so called template variables can be used to insert item data.

Example

An example

Templates: Items

An example for the item body template:

<h1><%title%></h1>

<p><%body%></p>

<div class="metadata">
 <a href="<%itemlink%>">link</a> -
 <%date%> <%time%> -
 <a href="<%authorlink%>"><%author%></a> -
 <%comments%>
</div>

The result would become something like this:

Templates: comments

There are three possible structures for a comments block.

1. When comments are displayed (like on detail pages, or on the main page when there are less than the maximum allowed amount of comments)

   comments header
     comments body (repeated)
   comments footer

2. When there are no comments at all

   no comments
   

3. When there are comments, but there are more than the maximum allowed number. (only applies when not on a detailed item page)

   too much comments
   

Inside these template-parts, some comments-related variables are available

Templates: Comment headers/footers

Description

While the comments-body is repeated for each comment, the header and footer are only displayed once. A typicall structure would look like this:

comments header
  comments body 1
  comments body 2
  comments body 3
comments footer

In these template-parts, comments-related templatevars are available

Examples

Header:

<ul>

Body:

<li><%user%>: <%body%></li>

Footer

</ul>

Result

• karma: nice!
• xiffy: yes indeed!

Templates: Link to extended entry

This is the template that will be used to format the morelink templatevar that is available in the item templates. Available variables are the same as in the item templates.

When there's no extended part of the item, the <%morelink%> templatevar will have no effect.

Example

<a href="<%itemlink%>">[Read More!]</a>

Templates: Archive Lists

The archive lists are formatted as listed below:

archivelist header
  archivelist listitem (repeated for each archive)
archivelist footer

Available variables: (in the header and footer, only blogid is allowed)

A more flexible way to add the date of the archive to the listitem, is to use strftime variables. If you find this too complicated, use the following:

<a href="<%archivelink%>">%B, %Y</a><br />

To change the language to your local settings, change the locale.

Templates: Category Lists

The category lists are formatted as listed below:

categorylist header
  categorylist listitem (repeated)
categorylist footer

Available variables: (in the header and footer, only blogid, blogurl and self are allowed)

View an example

Templates: Category Lists Example

(go back)

Header

<ul>
  <li><a href="<blogurl%>">All</a></li>

List Item

<li><a href="<%catlink%>"><%catname%></a></li>

Footer

</ul>

Results in:

• All
• myCategory
• yourCategory

Templates: Locale

This is actually not a template-part, it's a setting. Setting it allows the date and time preferences when to be localized. Names of months and days will be in the desired language, etc.

The possible values depend according to which machine Nucleus is running on. Some possible values are

• en: English
• dutch: Dutch
• ...

More info in the Open Group Specification for strftime. (opens a new window)

The locale is used for the date and time format, for the dateheaders, and for the archivelist items

Templates: Date and Time formats

These are used to format dates and times into the <%date%> and <%time%> vars (see template vars). The formatting is done according to the locale

More info on the available vars. If want to get started quickly, use "%x" to format the date and "%X" to format the time.

Template: Date headers/footers

The date header and date footer can contain date and time vars. More info on the available vars. If you want to get started quickly, use "%x" to format the date. The language which is used to format the date, is determined by the locale-setting in the template.

In the date header, the template variable <%%daylink%%> is allowed to insert a link to the archive for that day. Note the double '%'! It's necessary to avoid %d to be expanded as the current day of the month. Also, if you just want to add a '%' character somewhere, you should also put it twice ('%%') or it will be gone on your website.

Sample for date header:

<div class="day">
<h1>%d %B</h1>

Sample for date footer:

</div>

And another example for the date head using daylink

<div class="day">
<h1>%d %B</h1>
<a href="<%%daylink%%>">(archive)</a>

Templates: Highlight

The highlighting is used when performing searches. This is actually used in a regular expression, so you might want to escape some characters by putting a backslash before them. The place where the highlighted word will come, is indicated by "\0".

Example

<span style='background-color:yellow'>\0</span>

Templates: nothing found

Shown when a search has been performed and no results were found.

Available variables:

Example

No search results found for <b><%query%></b>

Templates: Comment body

This is the part of the template used to display a single comment. In this template-part, comments-related templatevars are available.

Example

<h2>Comment by <%userlink%>:</h2>

<p><%body%></p>

<div class="metadata">
 (from <%host%> on <%date%> at <%time%>)
</div>

Result:

Templates: Media & Popups

These templates are used to format links to popup image windows and media objects (non-pictures). The available variables for each of the templates are described below

Popup Link Code

Inline Image Code

Media Object Link Code

Templates: Member Extra

This is a template you can use to add an extra indication that a comment-author is a member. It ends up in the <%authtext%> variable for use in the comment body

Inside this template-part, some comments-related variables are available.

Templates: Comments Read More

This is the format of the link that will be added at the end of <%short%>, which is a variable for use in the comment body

Inside this template-part, some comments-related variables are available (except for the <%short%> variable).

Example:

 <a href="<%itemlink%>">[more]</a>

Templates: commentword

Most likely, you'll rather want to write "1 comment" than "1 comment(s)". The "One comment" and "Many comments" template parts can be used for this purpose. They will be used to fill the <%commentword%> variable that you can use elsewhere.

If there is only 1 comment, <%commentword%> will be equal to the contents of the "one comment" part. If there are many comments (more than one), <%commentword%> will be equal to the contents of the "two (or more) comments" part.

Typical values are "comment" and "comments". No special variables can be used here.

Templates: Edit Link

This template defines how the edit-templatevar will be marked up. You can use any of the template variables here.

Example:

<a href="<%editlink%>"
   onclick="<%editpopupcode%>">edit</a>

Skins: Main Index

This skinpart is used to show the most recent entries of your weblog. It's usually the home page of your site.

Very basic buildup for a main index:

<html>
  <head>
    <title>My Weblog</title>
  </head>
  <body>

    <h1>My Weblog</h1>
    <%blog(mytemplate,20)%>

  </body>
</html>

This will show the 20 most recent items of the default weblog (unless overridden), using the 'mytemplate' template.

Skins: Detail Pages

These pages are used to show the full items, all comments that were made and a form to add comments.

Very basic buildup for a detailed item page:

<html>
  <head>
    <title>My Weblog :: Item</title>
  </head>
  <body>

    <h1>Item</h1>
    <%item(detailed)%>

    <h1>Comments</h1>
    <%comments(detailed)%>

    <h1>Add Comment</h1>
    <%commentform%>

  </body>
</html>

This will show the item and comments using the 'detailed' template, and add a standard commentform.

Skins: Archive List

An overview of all the months for which archives are available, and links to those archives

Very basic buildup for an archive list:

<html>
  <head>
    <title>My Weblog :: Archives</title>
  </head>
  <body>

    <h1>Archives</h1>
    <%archivelist(default)%>

  </body>
</html>

This will show the list of all available archive files, using the 'default' template

Skins: Archive

An archive for one month. Behaves like a main index, but shows all the items from a certain month.

Very basic buildup for an archive page:

<html>
  <head>
    <title>My Weblog :: Archive</title>
  </head>
  <body>

    <h1>Archive</h1>
    <%archive(default)%>

  </body>
</html>

This will show the requested archive using the 'default' template

Skins: Search

Used to show search results.

Very basic buildup for a searchresults page:

<html>
  <head>
    <title>My Weblog :: Search</title>
  </head>
  <body>

    <h1>Search</h1>
    <%searchform%>

    <h1>Searchresults</h1>
    <%searchresults(default)%>

  </body>
</html>

This will show search results using the 'default' template.

Skins: Errors

Used when there is an error

<html>
  <head>
    <title>My Weblog :: Error</title>
  </head>
  <body>

    <h1>Error!</h1>
    <%errormessage%>

    <br /><br />

    <a href="javascript:history.back();">Back</a>

  </body>
</html>

This will show the error message, plus a link to go back.

Skins: Member

Used to show member details.

Very basic buildup for a member-detail page:

<html>
  <head>
    <title>My Weblog :: Member details</title>
  </head>
  <body>

    <h1>Info about <%member(name)%></h1>
    Website:
    <a href="<%member(url)%>"><%member(url)%></a>

    <h1>Send Message</h1>
    <%membermailform%>

  </body>
</html>

This will show the members name, website address and a mailform.

Skins: Image Popup

Used when a media file (image) needs to be shown in a popup window. This skin defines the layout that will be used in that case.

Very basic buildup for an imagepopup page:

<html>
<head>
  <title><%imagetext%></title>
  <style type="text/css">
   img { border: none; }
  </style>
</head>
<body>
  <a href="javascript:window.close();"><%image%></a>
</body>
</html>

Shortnames & Display Names

Weblogs, templates and skin should all have a short name next to the full name or description.

A short name consists of only the characters a-z and 0-9, and cannot contain spaces

Display names are used for members. They can contain a-z, A-Z, 0-9 and spaces, but the spaces cannot be placed at the beginning or end of the name.

Template: 'New' indication

When the 'last visit' cookie option is activated, the contents of the 'Indication of new item'-template is copied into the <%new%> variable for items that have been added since the last visit. The <%new%> variable can e.g. be used in the item body-template.

When the 'last visit' cookie is disabled, or the item is not 'new', this template part will not be used.

Time variables overview

The following conversion specifiers are recognized in the format string (taken from the PHP documentation for the strftime function). More info in the Open Group Specification

• %a - abbreviated weekday name according to the current locale
• %A - full weekday name according to the current locale
• %b - abbreviated month name according to the current locale
• %B - full month name according to the current locale
• %c - preferred date and time representation for the current locale
• %d - day of the month as a decimal number (range 00 to 31)
• %H - hour as a decimal number using a 24-hour clock (range 00 to 23)
• %I - hour as a decimal number using a 12-hour clock (range 01 to 12)
• %j - day of the year as a decimal number (range 001 to 366)
• %m - month as a decimal number (range 1 to 12)
• %M - minute as a decimal number
• %p - either `am' or `pm' according to the given time value, or the corresponding strings for the current locale
• %S - second as a decimal number
• %U - week number of the current year as a decimal number, starting with the first Sunday as the first day of the first week
• %W - week number of the current year as a decimal number, starting with the first Monday as the first day of the first week
• %w - day of the week as a decimal, Sunday being 0
• %x - preferred date representation for the current locale without the time
• %X - preferred time representation for the current locale without the date
• %y - year as a decimal number without a century (range 00 to 99)
• %Y - year as a decimal number including the century
• %Z - time zone or name or abbreviation
• %% - a literal `%' character

Ping Weblogs.com

When updating your weblog, you can choose to send an update notification (ping) to weblogs.com. This website provides a list of recently updated weblogs to everyone who requests it. Lots of websites are using this data, so you might receive some extra hits when enabling the ping.

Note: For this feature to work correctly, you need to fill out both the weblog URL and the weblog name in the blogsettings.

Always include in search

When the 'include in search' option is selected, the weblog will always be included in searches, even if the search is done on another weblog.

As an example, suppose you have two blogs called 'lifelog' and 'linkdump', with the 'include in search' enabled for 'linkdump'. Now, a search query on 'lifelog' will also search through 'linkdump', while a search query on 'linkdump' will only search entries in 'linkdump'

Convert Linebreaks

By default, Nucleus converts linebreaks in your items to <br /> tags, so a linebreak will also show up in your (X)HTML output

Advanced users, or users striving for the semantic web (br tags don't add any information, they're just used for markup), might find this feature annoying, and turn this feature off.

Media

Nucleus allows you to upload media files (images, video, sound, ...) to your website

Some settings are needed to do this:

• Media dir: location on the server where the media files will be saved (local filesystem)
• Media URL: location of the media files
• Allow upload: It's possible to disable file upload
• Allowed filetypes for upload: a bunch of extensions uploaded files can have (seperated by commas, case insensitive)
• Max. upload file size: Puts a limit on the size of uploaded files
• Prefix Media Files: When this option is turned on, uploaded file will be prefixed with the current date. Uploading a file named 'bunny.jpg' on April 8, 2003 will then result in a file named 20030408-bunny.jpg. The reason why you might want to do this, is when you're uploading tons of files, and don't want problems with duplicate names.

Each member has his own private collection of media files. Next to that, subdirectories that are under the media dir are seen as global collections (shared between members).

Uploading is only possible when a member is on the team of at least one of the blogs, to prevent abuse.

Protect Member Names

When this option is enabled, non-logged in members cannot add comments using the same name as registered members. The reason to do this would be to avoid guest impersonating members.

Plugin URL

This setting is the base URL for plugin admin areas. Usually it will look like the following

http://hostname.com/nucleus/plugins/

Skins URL

This setting is the base URL for the Nucleus skins directory. Usually it will look like the following

http://hostname.com/skins/

Action URL

This setting is the absolute URL of the action.php script that comes with Nucleus. Usually it will look like the following

http://hostname.com/actions.php

Adding items

When adding items to a weblog, there are four kinds of template variables that you can use in the body text, title or extended part:

• <%popup(...)%> to insert a popup image
• <%image(...)%> to insert an inline image
• <%media(...)%> to insert a media object

Usually, these tags are inserted by the 'insert media' button in the JavaScript toolbar

Notes

• This tag is affected by the parser settings IncludeMode and IncludePrefix

Arguments

• filename: the name of the file to be included (either relative to the position of index.php, or absolute)

Notes

• This tag is affected by the parser settings IncludeMode and IncludePrefix
• Your file will be included using the standard php include() command. This command will be called from inside a class method, so you'll need to declare which global variables you want to access yourself. Most of the standard variables are automatically declared global by Nucleus itself.

all

Examples

<%phpinclude(filename.php)%>
<%phpinclude(/home/user/myself/filename.php)%>

$HTTP_POST_FILES, $HTTP_ENV_VARS, $HTTP_SERVER_VARS
$HTTP_SESSION_VARS, $PATH_INFO, $HTTPS
$HTTP_RAW_POST_DATA, $HTTP_X_FORWARDED_FOR

For others variables, you'll need to add 'global $varname;' explicitly in your code

Skin/Templatevar: parsedinclude

Includes a file into the output. The contents of the file is parsed by the Nucleus skin/template parser, so you can use skin/templatevars. (see phpinclude and include for other include options)

Arguments

• filename: the name of the file to be included (either relative to the position of index.php, or absolute)

Notes

Template variables: Overview

What?

Template variables largely work in exact the same way as skin variables, with the only difference that they are being used inside templates. The variables are called using <%varname%>, and include some text depending on the variable function. Some variables also have extra optional parameters.

Available variables

These template variables be used in the following template-parts: item header, item body, item footer, date header, date footer, morelink, editlink (The variables image, popup and media can also be used inside weblog items.)

• Basic variables... (title, body, ...)
• Advanced variables... (include, plugin, ...)

Comments-related template-parts (comments header, comments body, comments footer, one comment, two comments, comments read more, no comments, too much comments) have a different set of available variables:

• Comments-related variables...

Template variables: Basic variables

All these variables concern the item that's currently being parsed.

Templatevar: karma

Inserts karma votes data. Karma votes are a method to vote the 'karma' of an item. With a single click, the visitor can vote either positive or negative. The total of all these votes gives an idea of how much an item is liked by the visitors

Arguments

Optional:
• what: Choose a type of information to be displayed:
  • totalscore: the total karma vote score (=amount of positive votes minus the amount of negative votes) (default)
  • pos: total number of positive votes
  • neg: total number of negative votes
  • votes: total number of votes
  • posp: percentage of votes that is positive
  • negp: percentage of votes that is negative

Examples

<%karma(posp)%> out of <%karma(votes)%> were positive

Templatevar: templateitemtitle

On comments-releated templateparts, inserts the title of the associated item.

Arguments

Optional:
• maxlength: When provided, makes the itemtitle behave like the syndicate_title templatevar.

Templatevar: author

Inserts the name of the author

Arguments

Optional:
• what: Choose a type of information to be displayed:
  • name: display name (default)
  • realname: the real name of the author instead of the display name
  • id: Nucleus membet ID
  • url: URL of members website
  • email: email address of member (use of this one should be avoided)

Examples

<%author%>
<%author(realname)%>
<a href="<%author(url)%>"><%author%></a>

Templatevar: smartbody

Examines the current item and then decides to show either the body text or the expanded text.

When the extended part is empty, the body part is chosen. Otherwise the extended part is shown.

Example use

The body text could be interpreted as your full text, and the extended part could be interpreted as an 'introduction' or 'exerpt', which you want to show on the front page.

In the template used on the front page, you would use <%smartbody%> to insert an excerpt (if there is one), or the full text (if no excerpt). In the template for detailed items, <%body%> can then be used instead of the usual <%body%> + <%more%>, since <%body%> will contain the full item anyway.

Templatevar: morelink

Inserts a link to the detail page for the item, as defined in the template (link to extended entry). This is empty when there is no extended part.

Note that the contents of the 'link to extended entry' templatepart is also parsed and can thus also contain templatevariables.

Templatevar: date

Inserts a date using the date format specified in the template. Optionally, a custom date format can be given as a parameter.

Arguments

Optional
• format: format to be used to format the date

Specials

Four special parameters are possible:

1. rfc822: RFC822 date in local time
2. rfc822GMT: RFC date in GMT time
3. iso8601: ISO-8601 date (W3C Date and Time Format profile). Example: 2002-10-02T10:00:00-05:00
4. utc: Same as iso8601, but the date is expressed in UTC, using a "Z" for the timezone indicator.

Examples

<%date%>
<%date(%x)%>
<%date(rfc822)%>
<%date(rfc822GMT)%>

Templatevar: time

Inserts a time using the time format specified in the template. Optionally, a custom time format can be given as a parameter.

Arguments

Optional
• format: format to be used to format the time

Examples

<%time%>
<%time(%X)%>

Templatevar: comments

Inserts a comments 'block'. More information about the structure of this block.

Arguments

Optional:

Name	Contents

Templatevar: syndicate_title

Inserts the title of the item, with HTML tags-stripped off, and shortened to 100 characters. When the text needs to be shortened, "..." is added at the end of the text.

This variable was originally intended for use in the XML-RSS skin that comes with Nucleus, but can also be of use in other situations.

Arguments

• Optional:

  Name	Contents
  MaxChars	Maximum amount of characters to keep (defaults to 100)

Examples

<%syndicate_title%>
<%syndicate_title(25)%>

This variable was originally intended for use in the XML-RSS skin that comes with Nucleus, but can also be of use in other situations.

Arguments

• Optional:

  Name	Contents
  MaxChars	Maximum amount of characters to keep (defaults to 250)

Examples

<%syndicate_description%>
<%syndicate_description(25)%>

Templatevar: image

Inserts an inline image into an item body or template.

In normal use, the image-templatevar is generated automatically when adding images through the media library. You can call it from within templates too, though. Note that in this last case, the image will come out of the media dir of the current item's author.

Arguments

• Required:

  Name	Contents
  filename	Name of the image file (file gets)
  width	Width of the image (pixels or percentage)
  height	Height of the image
  text	alt-text for the image

• Note: for the image, popup and media tags, the parameters must be separated by the '|' character, not by a comma!

Examples

<%image(myphoto.jpg|100|200|this is me)%>
<%image(myphoto.jpg|50%|50%|this is me, but smaller)%>

Templatevar: popup

Inserts a popup image into an item body or template.

In normal use, the popup-templatevar is generated automatically when adding images through the media library. You can call it from within templates too, though. Note that in this last case, the image will come out of the media dir of the current item's author.

Arguments

• Required:

  Name	Contents
  filename	Name of the image file (file gets)
  width	Width of the image (pixels or percentage)
  height	Height of the image
  text	alt-text for the image

• Note: for the image, popup and media tags, the parameters must be separated by the '|' character, not by a comma!

Arguments

• Required:

  Name	Contents
  filename	Name of the image file (file gets)
  text	descriptive text for the media object

• Note: for the image, popup and media tags, the parameters must be separated by the '|' character, not by a comma!

Examples

<%media(mysong.mp3|listen to my new song)%>

Templatevar: edit

From within your template, you can add an 'edit item' link by using this template variable. By default, it will link to a popup-bookmarklet-window, but that behaviour can be changed through the editlink template.

Note: only logged in members that are allowed to edit the item will see this link. In other cases, the edit-templatevar does nothing at all.

Example

An example for the item body template

<h1><%title%></h1>
<p><%body%> <%morelink%></p>
<div class="metadata">
	<%edit%> <%comments%>
</div>

Results in

Templatevar: editlink

Insert a link to the 'edit item' bookmarklet. This can be used in the editlink template for simplicity.

Example

The 'edit link'-template could look like this:

<a href="<%editlink%>"
   onclick="<%editpopupcode%>">edit</a> -

Templatevar: editpopupcode

To open a popup window for the 'edit link' window, you'll need to add some javascript code to your link. To avoid having to enter this code in the 'edit link'-template, you can insert it using the editpopupcode-templatevar.

Example

See the example for the editlink templatevar

Plugins

Nucleus allows you to install custom plugins, adding extra functionality. Plugins can do different things:

1. Act as a skin variable
2. Act as a template variable
3. Hook into events generated by Nucleus. The 'move up' and 'move down' links in 'manage plugins' screen can be used to define the order in which plugins will be called when such an event occurs. The first plugin in the list will be called first, the last one will be called last.
4. Act as actors when called through action.php

Note that the responsibility for plugins is entirely with the plugin author. He should make sure that everything works fine.

Parser Properties

The available parser options are described below.

The IncludePrefix and IncludeMode properties can be set globally for a skin in the general settings of a skin. Also note that from the moment a property is set, it applies to all parsed data, thus also for templates.
